I have to say, I'm a little impressed. Wasn't I just ranting about hating all the crap mail my mail slot fills up with on a weekly basis?
This isn't the total solution to this problem but it's a step in the right direction. My city government is working with Zumbox to transition from physical, analog postal mail to digital e-mail distribution! That's kinda cool. So anything that my local government would mail to me will instead go to my Inbox, where my Gmail will reckon with it handily. They're also pushing other big mailers (AT&T, Verizon, State Farm, &c.) to convert as well--that's less paper being printed and less fuel burned to produce and transport it.
I'm all in favor of this. I still want hand-written letters and postcards, but my junk mail and bills would serve me better as e-mail alerts rather than physical clutter.
